The problem is that you don't need to file form 1116 if your foreign tax credit is less than $600. Turbotax is smart enough to realize this (hence why it says don't file the form), but its still flagged as a problem and efile is still trying to file 1116 with my return. Please fix your software, so I can eFile my taxes.
Turbotax even says this on their website, but they have a broken tool when this occurs... Wtf
Actually, Line 33 should be the smaller of Line 20 (total tax amount) or Line 32. This line should not be blank, as it's the amount of tax TurboTax calculated on Form 1040, Line 16, plus any amount on Line 17.
If you're using TurboTax Desktop, if there's no amount on Form 1116, Line 20, check Line 16 and 17 on your Form 1040 and enter that amount. Then Line 33 on Form 1116 will have that amount also.
If you're using TurboTax Online, clear your Cache and Cookies first. Then you could delete Form 1116, and step through the interview for Foreign Tax Credit again to repopulate it. Here's How to Delete Forms in TurboTax Online.
I haven't encountered this same error, but with TurboTax Online data can get 'stuck', which is why you clear your browser.
